Why does the enzyme end with "ase"? Give an example of the type of that enzyme and its substrate. Which of the following statements about enzymes is false? A) Some enzymes change shape when they bind to their substrate. B) Enzymes lower the activation energy for a chemical...
Enzyme synthesis refers to the process where the presence of certain substances, such as substrates or hormones like steroids and thyroid hormones, triggers the production of enzymes in a cell. These newly synthesized enzymes can be further activated by other types of hormones like polypeptides. ...
Which of the following options is correct? Acid-fast staining is used to distinguish the following type of bacteria: a. Mycobacteria b. Bacillus c. Gram-positive bacteria d. Staphylococcus e. Spirochetes Which species of bacteria produce...
Combined GOx and EST can function as an OR logic gate, any of the substrates can be catalyzed to produce an acid which decreases pH and releases doxorubicin (Dox) from a mesoporous silica particle (Díez et al., 2014). Enzyme-based biocomputing systems can integrate multiple logic gates in ...

Rapid, inexpensive, robust diagnostics are essential to control the spread of infectious diseases. Current state of the art diagnostics are highly sensitive and specific, but slow, and require expensive equipment. Here we report the development of a mole
Questions 51 to 55 are based on the following passage. Scientists have created by accident an enzyme (酶) that breaks down plastic drinks bottles. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles. The new resear...
Answer to: Allosteric regulation occurs when an enzyme has a site that can bind an effector molecule separate from the active site. A. True B...
α-Amylase activity was assayed with the chromogenic substrate RBB-starch. An enzyme aliquot was incubated (20 min, 26°C) with 0.3% RBB-starch in 0.1 M Britton-Robinson buffer at the pH optimum of the enzyme (6.5 for Aca s 4 and A. siro extract, 7.0 for D. farinae extract, 6.9 ...
A major challenge in mathematical modeling of biological systems is to determine how model parameters contribute to systems dynamics. As biological processes are often complex in nature, it is desirable to address this issue using a systematic approach.
